We look at the division of 421110 by 28 
We want to figure out the number of times 421110 can be divided by 28.

Let's proceed to step 1:
28 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 28

Going ahead to step 2:
The number 28 fits into 42 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 14 after subtracting 28 from 42.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 28

Advancing to step 3:
When dividing 141 by 28, we get 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 1 after subtracting 140 from 141.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 28

Moving on to step 4:
If we divide 11 by 28, we get 0 and a remainder of 11.
The next digit of our result is 0. 
Result so far: 150.0
The remainder is 11 after subtracting 0 from 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 28

Let's proceed to step 5:
28 can be fit into 111 3 times, resulting in a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 1503.0
If we take 84 away from 111, we end up with 27.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 28

Step 6:
When dividing 270 by 28, we get 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 15039.0
Subtract 252 from 270 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
If we divide 180 by 28, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 15039.6
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
When dividing 120 by 28, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 15039.64
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 28 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 15039.642
If we take 56 away from 80, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 15039.6428
If we take 224 away from 240, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
28 can be fit into 160 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 15039.64285
Subtracting 140 from 160 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
28 goes into 200 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 15039.642857
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
The number 28 fits into 40 1 times, leaving a remainder of 12.
The next digit of our result is 1. 
Result so far: 15039.6428571
Subtracting 28 from 40 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
120 divided by 28 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 15039.64285714
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 15039.64285714 with a balance of 8e-09.
